y 11y claims. (c1. 117-34) This invention relates to improvementsinmachines for uniting a plurality of elements or serving coveringelements about a core element.

The principal objects of the invention are directed to the provision ina machine for uniting elements or for; serving or covering a coreelement with other elements of means wherein the elements are suitablyguided and tensioned for the uniting or covering operation. Variousnovel features and advantages of the invention will be more fullyhereinafter referredy to in connection with the accompanying descriptionof the novel combination and arrangement of parts constituting theinvention, reference being had to the accompanying drawing wherein;

Fig. 1 is an elevational view of an apparatus of the class describedhaving the novel features of the invention associated therewith.

Fig. 2 is a partialsectional view at a larger scale showing certainnovel features of the invention,

and

Fig. 3 is a fragmentary elevational view to explain certain features ofthe invention.

. Referring now to the drawing more in detail the novel features of theinvention will be fully described.

In Fig. 1 there is shown an apparatus which may consist of one ormore'spindle units indi-4 cated by 2 and 4. In the form of the inventionat present preferred two spindles are shown, one above the other andthey may be used to serve an outer element or elements about an innercore element as will appear, but it will be understood the apparatus maybe used to unite by twisting or throwing a number of elements.

Each of the spindle units. preferably lincludes a rotatable spindle 6which spindle in the form of the invention shown may be associated witha'rotating part of a motor enclosed within a housing 8 which is suitablysupported by frame 10. A v take-up member 12 which may be in the form ofa spool or drum is rotatable above the spindles and a transverselyreciprocating bar 14 as in the said application is provided for leadingthe nished product onto the take-up member. Guides 16 having openings 17therethrough are suitably supported by supporting structures 18 shownextending from the frame 10. y

The spindles 6 referred to are preferably hol- 'low to permit materialsuch as a core element y C to pass therethrough and have portions on`their upper ends to receive spools or packages represented by S. Thesespools or packages may have wound thereon yan1. filaments or other ele-Y spindle.

ments indicated by E, and will be called yarn packages.

A guide cap indicated generally by 20 is provided for each spindle andwill be described in detail to facilitate a clear understanding of thenovel features thereof. yThe cap has a body portion having a central hubportion 22 as shown which is suitably bored to t and receive the upperend 6' of the spindlevand is hollowed out as at 24 so thatits lower end25 isA in the form 65 of a skirt or flange to encircle the upper end ofthe yarn package S. Annular guideways 28, 30, 32, and 34 disposed oneabove the other are provided on the cap and decrease in diameter'upwardly from the lower one. Travelers t which maybe more or lesscircular in shape as shown in Fig. 3 are slidable around the annularguideways. The cap is removable from the `spindle to permit packages tobe placed on and taken off the To facilitate aclear understanding of theoperaltion of the cap it will be assumed that a core C in the form of ayarn or filament of metal or rubber is being passed upwardly through thespindles 6 and onto the take-up spool and that 80 it is desired to coveror serve the core with covering elements or filamentsdwhich may becarried by the yarn packages. The filaments from the packages are passedupwardly through the travelers t and onto the core C. With the spindlesin rotation the lpackages S will be rotated as will the caps 20 so thatthe elements will be carried around and wound or served about the core.As will be seen with particular reference to Fig. 3 an element E isguided at'spaced intervals from a point adjacent the upper end of thespool to anupper point adjacent where it passes onto the core wherebythe element is held against ballooning.

A cap rotates with its spindle so that theA relative movementsbetweenthe travelers and the guideways therefore is not great, at least onlyenough to allow the core to take up the element, or allow the element tobe wound-about the core. Therefore appreciable frictional. actionbetween the travelers and the guideways is eliminated as distinguishedfrom the condition where a trav' eler slides around a non-rotatingguideway. This is all to the end that a very delicate element may bewound onto the core without 4being burdened with excess tension andmakes it possible to Wind an element about the core with the desireddegree of tension and uniformity and without such over tension as willeither cause the elebear. As shown in Fig. 3 as a somewhat ilatfilavwill strain the laments about the core a-guiding horn 39 is.

provided at the upper side ofthe cap which has a rounded end or roundedcircumferential ironing surface y41 against `which the filament may menttravels around the edge 41 and upwardly onto the core it is flattenedout or turned so that it is guided in lproper position and withouttwisting as it passes onto the core.

It may be desirable in some cases to provide packages with amultiplicity of separate elements or ends wound thereon. In such'a caseone of the elements may be passed upwardly. through one or more of thetravelers t while another element may be passed upwardly through one ormore of the other travelers t all to the end that one end or filamentmay be guided independently pf another and onto the core, each with thepropery tension and in the manner desired, held against ballooning. i

As will be seen an element E is taken on by *the core C at apointbetween the lower end of the guide 16 and the upper end of the cap20 and the uppermost traveler operates to guide an element in closeproximity to the point where the elementand core are united. The elementbetween the upper and lower travelers is held..

vide the lubrication therefore.

In some cases it may be desired instead of covering a central coreelement with a covering element to twist or throw an element from onespool with an element of another spool or to twist elements of eitherspool with one or more of those of another spool.l This may beaccomplished by bringing the elements together above the cap and passingthem through the travelers. l

From the foregoing, it will be apparent that the apparatus is adapted toinsure accuracy and excellence of product in connection with operationswhere it is desired to unite elements of various materials. It isdesired therefore to be limited, if at all, by the appended claimsrather than by the foregoing description. What I desire to claim andsecure by Letters Patent of the United States is:
